Product details

Lightweight bum bag for hiking, travel and everyday use

This Mayoii bum bag is for people who like to keep moving — hands-free, light on their feet and without faffing about with pockets. It’s aimed at walkers, runners, festival-goers and anyone after a simple, reliable carry solution that doesn’t add bulk. The khaki finish is neat and understated, so it slots into city, countryside or holiday wardrobes without any fuss.

Practical design that just works

There are two main zip compartments for everyday essentials plus a small hidden pocket for cards or cash. The zip pulls are easy to use whether you’re wearing gloves on a blustery autumn morning or fidgeting quickly on a platform before a train. The waist strap is adjustable, so it sits comfortably on most bodies and can be worn on the hip, at the front or across the chest as a sling.

  • Lightweight – marketed as ultra-light; around 100–110 g in real use, so it won’t weigh you down.
  • Water-resistant fabric – shrug off light rain and sweaty workouts, but it’s not meant for full submersion.
  • Comfort-first cut – breathable backing and an ergonomic shape reduce bounce when jogging or hiking.
  • Secure storage – two zip pockets plus a concealed pocket for valuables.
  • Versatile wear – adjustable belt fits a range of sizes and wearing styles.

Typical uses and benefits

Out for a day hike or a quick run? This bum bag keeps your phone, keys and cards close at hand without rubbing or bouncing. Travelling? It’s ideal for boarding passes and passport pages. At festivals it frees your hands for dancing (or carrying a drink). No more rummaging through a rucksack for small bits — everything’s where it should be.

Bear in mind the capacity: it’s compact, so it won’t replace a daypack, but for essentials it’s bang on. Also: the water-resistant fabric gives peace of mind in a drizzle, but in a proper downpour you’ll want extra cover for electronics.
